FCC certification testing standard for liquid crystal displays

FCC certification testing standard for liquid crystal displays. Liquid crystal display (LCD) is an active matrix LCD display driven by thin film transistors (TFT). It mainly uses electric current to stimulate LCD molecules to produce dots, lines, and surfaces, which are combined with the back light tube to form a picture. IPS, TFT, and SLCD are all subcategories of LCD. But generally, to export this type of product to the United States, it is necessary to apply for FCC certification.

Display FCC certification

The list of documents and requirements required for FCC certification of liquid crystal displays are as follows:

1. FCC Application Form: The applicant's company name, address, contact information, product name and model, and usage standards must be accurate and accurate;

2. FCC authorization letter: must be signed and stamped by the contact person of the applying company and scanned into an electronic file;

3. FCC Confidentiality Letter: A confidentiality letter is an agreement signed between the applicant company and TCB organization to keep product information confidential. It must be signed, stamped, and scanned into an electronic file by the contact person of the applicant company;

4. Block diagram: All crystal oscillators and crystal oscillator frequencies need to be drawn and consistent with the circuit diagram;

5. Circuit diagram: It must be consistent with the crystal oscillator frequency, number of crystal oscillators, and crystal oscillator position in the block diagram;

6. Circuit description: It is required to be in English and clearly describe the functional implementation principles of the product;

7. User manual: FCC warning language is required;

8. Label and label location: The label should have an FCC ID number and a Statement, and the location of the label should be significant;

9. Product interior and exterior photos: The images should be clear and clear, and additional remarks should be added if necessary;

10. Test report: It is required to complete the test and comprehensively evaluate the product according to standard terms;

FCC certification steps and processes for liquid crystal displays

1. The customer submits an application form (our company provides a blank application form);

2. The client signs a commission testing contract with our company;

3. Send samples for testing and prepare electrical schematic diagrams, external/internal photos, oscillator circuit diagram, user manual nameplate identification, working principle instructions, etc. (depending on the product);

4. After passing the inspection, if it is FCC VOC certification, our company will directly issue a certificate of conformity and a report. If it is FCC DOC or ID certification, our company will submit the application materials to the FCC authorized certification agency;

5. After obtaining FCC certification, enterprises can use the FCC logo on their products.

How long does it take for LCD display FCC certification?

The FCC certification time for connecting devices should be 3-5 weeks. To expedite this process, FCC certification can be received within 1-2 weeks.
